Changing the curser size in KMymoney under Linux Mint
Have you tried changing the cursor is the system settings program? I don’t believe KMyMoney exerts any control over the cursor size.
Yes, the curser on the desktop is fine just when I scroll over to the KMyMoney screen it gets miniscule.
Which version of KMyMoney do you use? Do you use HiDPI mode in your environment? Do you use X11 or Wayland? Where did you get the KMyMoney version you are running (which URL)? I know, a lot of questions, but as @ostroffjh pointed out: KMyMoney code does not modify the cursor size.
